Excelent work!

Hi,

I have searched a lot for a working plugin like this to integrate with nagios 3.4 and nagiosgraph.
From many tested this is the only one working for me that is also generating perfdata.
I have chosed to change my ” $bitmod = BYTES; ” to ” my $bitmod = BITS; ” and here is an example of usage in my case: ” /usr/bin/perl /root/check_if.pl -i eth1 -w 700m -c 900m -b 1000m ” (this is for a gigabit interface)

Nice work for the author!
